MiniDiscs were used in Canada to record, store and play back audio files. "MiniDiscs" était utilisé au Canada pour enregistrer, stocker et jouer des fichiers audio.
Function
To record, store and play back audio files. Enregistrer, stocker et jouer des fichiers audio.
Technical
Introduced by Sony in 1992, the MiniDisc was a compact and portable magneto-optical data storage device that was mainly used to record, store and play back audio files. Eventually reaching a capacity of 80 minutes of digitized audio or 1 gigabyte of data, the MiniDisc was developed to be used with portable listening devices. A MiniDisc was recorded on, and erased, by using a laser and a magnetic head. The laser altered the magnetic coercivity to erase previous data, allowing the magnetic head to impart a new bit pattern through positive or negative polarization. MiniDisc technology employed digital compression to reduce storage requirements by a factor of 5 to 1.While MiniDiscs were popular in Japan, they had restricted uptake in Canada where they were mostly limited to specific professional applications like journalism. Intended as a mainstream replacement for compact analogue magnetic cassettes and Compact Disks, the MiniDisc’s high cost was ultimately unable to compete with magnetic cassettes, CDs, MP3s, DVDs and flash drives. Sony ceased production of MiniDiscs in 2011, and the last MiniDisc players were sold in 2013. Introduit par Sony en 1992, le MiniDisc était un appareil de données magnéto-optiques compact et portable qui était utilisé principalement pour enregistrer, stocker et jouer des fichiers audio. Éventuellement atteindre une capacité de 80 minutes d'audio numérisée ou 1 gigabyte de donnés, le MiniDisc a été développé pour être utilisé avec des appareils d'écoute portatif. Le Minidisc a été enregistré, et effacé, en utilisant un laser et une tête magnétique. Le laser changeait la coercivité magnétique pour effacer les données précédentes, permettant à la tête magnétique de donner un nouveau patron à travers une polarisation positive ou négative. La technologie MiniDisc utilise la compression numérique pour réduire les besoins de stockage par un facteur de 5 à 1. Quoique MiniDiscs était populaire au Japon, ils ont connu une utilisation restreinte au Canada ou ils ont été limité à des applications professionnelles spécifiques comme journalisme. Prévu en étant un remplacement pour les cassettes magnétiques analogiques compactes et les disques compacts, le coût élevé du MiniDisc était incapable de compétionné avec les cassettes magnétiques, CD, MP3, DVD et lecteur Flash. Sony a arrêté la production de MiniDiscs en 2011; et le dernier Minidiscs a été vendu en 2013.
